What are the legal risks of practicing laser cutaneous surgery?
The physician-patient relationship is a key factor in preventing litigation following cutaneous laser surgery, according to Mathew M. Avram, MD, JD.
“Numerous studies indicate that good communication and rapport are the most important means to avoid a lawsuit,” Dr. Avram, director of laser, cosmetics, and dermatologic surgery at Massachusetts General Hospital, Boston, said during a virtual course on laser and aesthetic skin therapy. “It is helpful to say that the outcome was not optimal or what you were anticipating. Communicate your plan [for the complication] clearly and honestly to your patient. The patient may not understand the severity of the complication. If they don’t, they will either leave it alone or they will go elsewhere and may receive poor care.” He added that in New England, “we have some stoic patients who may say ‘I don’t want to bother the doctor’ or ‘It’s my fault for having the procedure done.’ ”
Establishing effective communication with patients from the outset is good practice, he continued, because 75% of physicians in low-risk specialties will face a malpractice claim by age 65. Nearly a decade ago Dr. Avram, H. Ray Jalian, MD, and Chris Jalian, JD, published results from a national legal database analysis identifying common errors and risk factors for litigation in cutaneous surgery. Their search yielded 1,807 documents with 174 unique legal claims involving injury from a cutaneous laser treatment, from 1985 to 2012. The most common litigated procedures were laser hair removal, rejuvenation (mostly related to intense pulsed-light treatments), and laser treatment of leg veins, while the most common injuries sustained were burns, scars, and pigmentary changes. The most common causes of legal action were lack of informed consent and fraud.
Among the 120 cases with public decisions, cases favored the plaintiff 51% of the time. “That’s unusual,” said Dr. Avram, president of American Society for Dermatologic Surgery. “Usually, physicians do better, but I think the fact that they’re cosmetic cases probably shades things a little bit.” The median monetary award was $350,000 and ranged from $5,000 to $2,145,000. The two largest judgments were for improper use of topical anesthesia that led to deaths of patients in laser hair removal cases.
In a separate analysis, the same authors searched an online national database to identify the incidence of medical professional liability claims resulting from cutaneous laser surgery performed by nonphysician operators (NPOs) from 1999 to 2012. Among the 175 cases identified, 43% involved an NPO. “In fact, the cases involving NPOs exploded over a 4-year period; they grew from 36% in 2008 of cases to 78% in 2011,” Dr. Avram said. “This was even more true for laser hair removal.”
The practice setting turned out to be a factor. Only 23% of NPO litigation involving laser procedures arose in medical office settings, while 77% of cases involving NPOs were performed outside of traditional medical settings such as in salons and medical spas – mostly for laser hair removal. “We updated this information by examining the setting for nonphysician operator litigation between 2012 and 2017 and found that 66% of cases involving NPOs were performed outside of a traditional medical setting, while 34% of NPO litigation arose in medical office settings,” Dr. Avram said during the meeting, which was named What’s the Truth? and sponsored by Harvard Medical School, Massachusetts General Hospital, and the Wellman Center for Photomedicine. “That’s close to a 2 to 1 ratio.”
In an analysis of medical professional liability claims involving Mohs surgery from 1989 to 2011, 26 of the 42 cases identified involved a primary defendant who was not a Mohs surgeon. In the 26 cases, the most common reasons for lawsuits were failure or delay of diagnosis of a skin cancer, cosmetic outcome issues, lack of informed consent, and delay or failure to refer to a Mohs surgeon. Of the cases that involved Mohs surgeons, the most common causes were lack of proper informed consent and cosmetic outcome issues, but “these cases were overwhelmingly decided in favor of the surgeons,” said Dr. Avram, one of the study authors.
On a related note, Dr. Avram underscored the importance of biopsy-site photography, “because patients and physicians misidentify biopsy sites too commonly,” he said. In a single-center study of 34 biopsy sites of cutaneous head and neck malignancies, patients misidentified the biopsy site 4-7 weeks out in 29% of the cases. Blinded dermatologists and the patient misidentified the biopsy site in 12% of the cases. “Good biopsy site photography should be mandatory in your practice,” he advised.
Clinicians can avoid cutaneous laser surgery complications only by not treating patients. “Complications and side effects are inevitable; you need to know your limits,” he said. “Even in skilled hands, if you treat enough patients, you will encounter challenging side effects. Do not perform a procedure that might produce a side effect that you cannot recognize and treat.”
The best way to avoid complications is to trust your eyes – not the laser – since the same device made by the same manufacturer may produce highly different outputs at the same setting (see J Am Acad Dermatol. 2016;74[5]:807-19).
“Moreover, lasers can produce much different energies after they have been serviced,” Dr. Avram said. “Do not memorize settings. Do not blindly replicate recommended settings from a colleague or a device manufacturer,” he advised. “Some devices are not externally calibrated. Therefore, the settings on one device may not translate the same way to yours. Often, device manufacturers underplay the settings. Safe and unsafe laser endpoints and close observation are the best means to avoiding clinical complications. That means you follow clinical endpoints, not fluences. The key clinical finding is the endpoint, not the energy setting.”
Temporary and expected side effects include erythema, edema, and purpura. “With these it’s just handholding and unlikely to lead to any legal consequences,” he continued. “With temporary hyperpigmentation that can occur with laser hair removal, time is one your side, because typically this will resolve before any litigation progresses. Permanent side effects from lasers and light sources and injectables are a different issue, things like permanent hypopigmentation, depigmentation, and scarring. These are most likely to produce liability.”
In Dr. Avram’s opinion, complications are best handled with widespread communication. “There is a temptation to avoid a patient with a poor outcome or side effect,” he said. “This is bad medicine and rightfully angers your patient and increases the risk of a lawsuit. [Resist] the temptation to avoid showing a poor outcome to a colleague. Many complications can be significantly improved or cleared with timely and appropriate interventions. You should always document your efforts.”
Dr. Avram disclosed that he has received consulting fees from Allergan and Galderma. He is a member of the scientific advisory board for Allergan and Soliton, is an investigator for Endo, and holds stock options in La Jolla NanoMedical Inc.

FROM A LASER & AESTHETIC SKIN THERAPY COURSE
Expert shares eye protection tips for cutaneous laser surgery
Suzanne L. Kilmer, MD, will never forget the day when the center of her vision became blurry after performing cutaneous laser surgery.
The laser light reflected off the patient’s protective eye shield and caused a photo-induced foveal injury to Dr. Kilmer’s eye even though she was wearing protective goggles. “It was like the central part of my vision was browned out,” Dr. Kilmer, director of the Laser and Skin Surgery Center of Northern California, Sacramento, recalled during a virtual course on laser and aesthetic skin therapy. “My injury completely resolved, but you may not get so lucky. You can really get into trouble with longer pulse widths and higher-energy lasers.”
The injury occurred, she said, because the goggles she wore were sufficient for 1,064-nm wavelengths, but she was treating the patient with a 532 nm–wavelength laser. “I did not have the protection I needed,” she said. “You have to make sure to check the glasses yourself before you treat so that what happened to me doesn’t happen to you.”
Dr. Kilmer, who is also a clinical professor of dermatology at the University of California, Davis, said that during cutaneous laser surgery, “we want to pay attention all the time to minimize our risk.” She also recommended to make sure “all personnel in the room have had good safety training and have baseline eye exams. The door needs to be closed. The windows need to be covered, and you need a warning sign on the door that contains the specific wavelength, pulse width, and energy being used.”
The most important element of the sign, she added, pertains to the wavelength, because that determines the most appropriate goggles or eyewear to use “to ensure that you have an optical density high enough to protect your eyes.”
She advised using only eyewear designed for the specific laser wavelength being used, and to check the optical density prior to firing the laser. “You want the optical density to be greater than 4-6; you want as much protection as possible,” Dr. Kilmer said. “If you’re using a 1,064-nm laser and a 532-nm laser, you want glasses that protect you from both of those wavelengths. Multi- and dual-wavelength glasses are now available. The newer eyewear also allows you to see much better so there’s less risk with you taking it off the goggles [during the procedure].”
Dr. Kilmer recommends keeping a set of goggles outside of the procedure room door that matches every set of goggles being used in the room. “In one room, you may have several different lasers,” she said. “So you want some way to ‘attach’ the goggles to that particular laser, whether it’s a tray or some type of a coding system – some way to keep those together.”
For eye shield protection, the David-Baker lid clamp and the Jaeger plate are appropriate for ablative laser resurfacing, but most dermatologists use individual steel eye shields that are placed externally or internally. “Make sure you have different-sized eye shields on hand,” she advised during the meeting, which was named What’s the Truth? and sponsored by Harvard Medical School, Massachusetts General Hospital, and the Wellman Center for Photomedicine.
“Depending on what you’re performing, you will need anywhere from neonate size to larger adult size. Some adults may require child-size shields,” she said, noting that there are external eye shields that can be cleaned after each use. “But we tend to use LASER-Aid disposable eye shields, which have metal in the middle and stick over the eyelid. You only use these when you’re working outside of the orbital rim. If you’re treating within the orbital rim, you have to use an internal eye shield.”
She reported having no relevant financial disclosures related to her presentation.

Evaluations of novel approaches to treating NF-1 tumors are underway
In the clinical experience of R. Rox Anderson, MD, currently available treatment options for benign tumors caused by neurofibromatosis type 1 (NF-1) are not acceptable.
“Simply removing the tumors with surgery is not the answer,” Dr. Anderson, a dermatologist who is the director of the Wellman Center for Photomedicine at Massachusetts General Hospital, Boston, said during a virtual course on laser and aesthetic skin therapy. “We need a way to inhibit the cutaneous neurofibromatosis early in life and prevent disfigurement that occurs when kids become adults.
“Kids with NF-1 are born looking normal,” he said. “They have café au lait macules and Lisch nodules in their eye, but they’re normal-looking kids. By early adulthood, many will grow hundreds of tumors that are disfiguring.”
In patients with NF-1, surgical excision works for cutaneous tumors but is expensive and not widely available, and is usually not covered by health insurance. “Plus, you have these adults who have already been through a lot of trauma, with the disfigurement in their lives, who have to be put under general anesthesia to remove a large number of tumors,” Dr. Anderson said at the meeting, which was named What’s the Truth and was sponsored by Harvard Medical School, Massachusetts General Hospital, and the Wellman Center for Photomedicine. Cryotherapy is a minimally invasive way to treat cutaneous neurofibroma tumors, “but this destroys the overlying skin, so you get unwanted destruction,” he said. “I like the idea of selecting heating, but we don’t know yet by what method.”
Dr. Anderson and his colleagues just launched a comparative clinical They plan to perform one or more treatment methods per patient in a single treatment session, then follow up at least 6 months later. Baseline and untreated cutaneous NF lesions will serve as controls. The researchers plan to conduct three-dimensional imaging, clinical assessments, and evaluate pain and other subjective measures.
Use of deoxycholate in a pilot trial was well tolerated and induced tumor regression in adults with cutaneous NF, he said.
Dr. Anderson noted that other researchers are studying the potential role of topical or local mitogen-activated protein kinase (MEK) inhibitors for these tumors. “Systemic MEK inhibitors are effective for plexiform neuromas, but cause significant cutaneous side effects,” he said. A “soft” MEK inhibitor, NFX-179 is rapidly metabolized such that high drug levels are achieved in skin without systemic drug levels. However, Dr. Anderson said that it remains unclear if this approach will prevent cutaneous NF tumors from forming, arrest their growth, or induce their regression.
Dr. Anderson reported having received research funding and/or consulting fees from numerous device and pharmaceutical companies.
Commentary by Lawrence F. Eichenfield, MD
Neurofibromatosis type 1 (NF1) is a common genodermatosis, associated with the development of neurofibromas derived from nerves, soft tissue, and skin. Cutaneous NFs often develop in later childhood onward and may be deforming, associated with pruritus, pain, and significant effect on quality of life. Dr. Anderson is a world leader in laser treatment, having developed the theories behind laser development for medical usage, as well as the laser technology used for vascular birthmarks and hair removal, laser and cooling techniques targeting fat, and “fractionating” laser energy, which has revolutionized scar management. We look forward to his group’s insights into better management of NF1 lesions!

In the clinical experience of R. Rox Anderson, MD, currently available treatment options for benign tumors caused by neurofibromatosis type 1 (NF-1) are not acceptable.
“Simply removing the tumors with surgery is not the answer,” Dr. Anderson, a dermatologist who is the director of the Wellman Center for Photomedicine at Massachusetts General Hospital, Boston, said during a virtual course on laser and aesthetic skin therapy. “We need a way to inhibit the cutaneous neurofibromatosis early in life and prevent disfigurement that occurs when kids become adults.
“Kids with NF-1 are born looking normal,” he said. “They have café au lait macules and Lisch nodules in their eye, but they’re normal-looking kids. By early adulthood, many will grow hundreds of tumors that are disfiguring.”
In patients with NF-1, surgical excision works for cutaneous tumors but is expensive and not widely available, and is usually not covered by health insurance. “Plus, you have these adults who have already been through a lot of trauma, with the disfigurement in their lives, who have to be put under general anesthesia to remove a large number of tumors,” Dr. Anderson said at the meeting, which was named What’s the Truth and was sponsored by Harvard Medical School, Massachusetts General Hospital, and the Wellman Center for Photomedicine. Cryotherapy is a minimally invasive way to treat cutaneous neurofibroma tumors, “but this destroys the overlying skin, so you get unwanted destruction,” he said. “I like the idea of selecting heating, but we don’t know yet by what method.”
Dr. Anderson and his colleagues just launched a comparative clinical They plan to perform one or more treatment methods per patient in a single treatment session, then follow up at least 6 months later. Baseline and untreated cutaneous NF lesions will serve as controls. The researchers plan to conduct three-dimensional imaging, clinical assessments, and evaluate pain and other subjective measures.
Use of deoxycholate in a pilot trial was well tolerated and induced tumor regression in adults with cutaneous NF, he said.
Dr. Anderson noted that other researchers are studying the potential role of topical or local mitogen-activated protein kinase (MEK) inhibitors for these tumors. “Systemic MEK inhibitors are effective for plexiform neuromas, but cause significant cutaneous side effects,” he said. A “soft” MEK inhibitor, NFX-179 is rapidly metabolized such that high drug levels are achieved in skin without systemic drug levels. However, Dr. Anderson said that it remains unclear if this approach will prevent cutaneous NF tumors from forming, arrest their growth, or induce their regression.
Dr. Anderson reported having received research funding and/or consulting fees from numerous device and pharmaceutical companies.

Neurofibromatosis type 1 (NF1) is a common genodermatosis, associated with the development of neurofibromas derived from nerves, soft tissue, and skin. Cutaneous NFs often develop in later childhood onward and may be deforming, associated with pruritus, pain, and significant effect on quality of life. Dr. Anderson is a world leader in laser treatment, having developed the theories behind laser development for medical usage, as well as the laser technology used for vascular birthmarks and hair removal, laser and cooling techniques targeting fat, and “fractionating” laser energy, which has revolutionized scar management. We look forward to his group’s insights into better management of NF1 lesions!

FROM A LASER & AESTHETIC SKIN THERAPY COURSE
One of the keys to success on social media? Entertain and educate the public
Social media isn’t everyone’s cup of tea, but
“I admit that I’m somewhat obsessed with it. I kind of blame it on my work as a dermatologist, that I’m trying to grow my social media as well. It’s interesting to me, fascinating, and I want to understand it more. I think that’s the mindset you need to approach it with.”
Perhaps no other public figure in dermatology has enjoyed success in social media more than Dr. Lee, a board-certified dermatologist who practices in Upland, Calif. In the fall of 2014, she started using Instagram to provide followers a glimpse into her life as a dermatologist, everything from Mohs surgery and Botox to keloid removals and ear lobe repair surgeries. From this she formed her alter ego, “Dr. Pimple Popper,” and became a YouTube sensation, building 7.1 million subscribers over the course of a few years, amounting to 4.5 billion lifetime views. She also grew 12 million followers on TikTok, 4.4 million followers on Instagram, 3 million on Facebook, and more than 139,000 on Twitter. About 80% of her followers are women who range between 18 and 40 years of age.
During the meeting she offered five social media marketing tips for busy clinicians:
You have to ‘play’ to ‘win.’ Active participation in social media is required to develop followers. “You cannot delegate this content,” Dr. Lee said. “You can hire people to help you or leave the task to a social media-savvy medical assistant in your office, but the content should be your responsibility ultimately, because you are the physician,” she added. Not everyone chooses to participate in social media, but it’s also something not to shy away from out of intimidation. “There is some talent associated with it, but it takes a lot of persistence as well,” she said.
Patients come first. Protect them at all costs. Dr. Lee rarely posts the faces of patients she cares for unless they grant consent in advance. “I try to show the work that I do and the beauty of dermatology,” she said during the meeting, which was named “Laser & Aesthetic Skin Therapy: What’s the Truth?” and was sponsored by Harvard Medical School, Massachusetts General Hospital, and the Wellman Center for Photomedicine. She added that taking part in social media can help you improve communication skills by engaging with followers who like, share, or respond to the material posted. “When you look back at your posts objectively, you learn about yourself and how you relate to your patients,” she said. “It helps to hone my bedside manner and my skills as a dermatologist.”
Show that you are human. Many dermatologists and other “skin influencers” have established their presence on the Internet and may be direct competitors for patients, but that doesn’t mean you can’t establish your own identity. One way to stand out is by posting content related to your authentic self, such as a photo or video that shows you engaged in a hobby, dining at a favorite restaurant, or visiting a beloved vacation spot. “Your followers don’t want a robot, someone who thinks they’re amazing and can do everything,” said Dr. Lee, who stars in her own TV reality show on TLC. “Show that you have a funny side. You want them to fall in love with you and see a little bit of your world, whatever it might be. Charm the socks off of them.”
Entertain first, educate a close second. The main way you’re going to get people to follow and watch you is to provide some entertainment, “not at the expense of a patient or your practice, though,” she said. “Then you’re going to educate people. We dermatologists have something to teach the world because we are experts on skin, hair, and nails. You want to impart this knowledge in a way that captivates people.” It’s like the sense of accomplishment that comes from learning something new after reading a book or watching a movie, she explained. “You feel good about it, and you can take that knowledge with you somewhere else. I love it when kids come up to me and tell me they know what a lipoma is, what a cyst is, and what psoriasis is because they’ve seen my show, or because they follow me on social media. It’s wonderful because I can see that I’ve educated them.”
Be kind and don’t activate the trolls. Dr. Lee allows positivity and kindness to rule the day on her social media content. “This is what I try to relay to followers, but I also do not engage with the negativity,” she said. “Every now and then, there will be someone who tries to insult what you do or who insults you personally. If you engage with them, it almost invites them to do it more. It almost gives them the ability to fight with you. Try to stay above that; just put out goodness and kindness.”
Several years ago, YouTube and Instagram temporarily shut down Dr. Lee’s accounts because she posted graphic images of skin lesions and procedures – a practice that wasn’t so commonplace at the time. “Don’t just post a graphic image just to be graphic,” she advised. “Make sure it has an educational message associated with it. That will help to validate your content. Posting a warning sign that some images may be graphic could help, too.”
Dr. Lee reported having no relevant financial disclosures.

FROM A LASER & AESTHETIC SKIN THERAPY COURSE
Treatment with novel laser in acne studies targets sebaceous glands
at 12 months, a development that indicates the promise this has a treatment for acne in the future.
Currently, “there is no strong evidence that lasers are better than conventional treatments for acne,” Fernanda H. Sakamoto, MD, PhD, said during a virtual course on laser and aesthetic skin therapy. Some patients struggling with acne “search for so many different options and they end up spending a lot of money,” which, she said, includes an estimated $222 million for laser treatment alone in 2019.
Unlike other existing laser and light options for acne treatment, however, Accure is the first light-based platform to selectively target and injure sebaceous glands, the main source of sebum production and the key to a durable solution for acne. The laser, which uses a 1,726-nm wavelength, is being developed by researchers at the Wellman Center for Photomedicine, at Massachusetts General Hospital, Boston and was granted the European CE mark, which allows marketing of the product in Europe, in May of 2020.
In 2012, Dr. Sakamoto, a dermatologist at the center, and her Wellman colleagues were the first to describe the use of selective photothermolysis to target sebaceous glands. “We found that the peak absorption of lipids in sebaceous glands occurs between 1,700 and 1,720 nm,” she said. “Compared to water, the contrast is not high, so for us to develop a laser that is selective for acne, we needed to develop a strong cooling system and we had to create different methods to make it more selective.” She said that it took about 10 years to develop this laser.
The latest Accure prototype features a smart laser handpiece for real time thermal monitoring and precise delivery of laser emissions. “We have developed a mathematical model which permits us to predict safe and effective treatment patterns,” Dr. Sakamoto said at the meeting, which was named “Laser & Aesthetic Skin Therapy: What’s the Truth?” and was sponsored by Harvard Medical School, Massachusetts General Hospital, and the Wellman Center for Photomedicine. “It has a unique cooling system that can control and protect the skin.”
The clinical trial for Food and Drug Administration clearance, which was delayed because of the COVID-19 pandemic, is still underway, she said, and the hope is that the laser will cleared by the FDA by next year. She and her Wellman colleagues have been working with four veteran dermatologists to conduct clinical trials of the device: Emil Tanghetti, MD, in California; Roy Geronemus, MD, in New York; Joel Cohen, MD, in Colorado; and Daniel Friedmann, MD, in Texas. As of Oct. 2, 2021, more than 50 patients were enrolled in four IRB-approved studies and an additional 30 are enrolled in a pilot facial acne trial, Dr. Sakamoto said. In the trials, patients are followed at 4, 8, 12, and 24 weeks post treatment.
Among patients enrolled in the pilot facial acne trial, researchers have observed a 100% responder rate for patients with more than five acne lesions at 4, 8, 12, and 24 weeks post treatment. The average lesion reduction at week 12 was 82% and the mean Visual Analog Scale score immediately after treatment was 2.10 out of 10. Each patient received more than 12,000 trigger pulls of energy from the device with no adverse events.
“This laser is absorbed in the near-infrared spectrum, so there is no melanin absorption,” Dr. Sakamoto explained. “It’s pretty much a color-blind laser, so we can treat darker skin types safely, with no side effects.” In other findings, researchers observed a 45% reduction in acne lesions after one treatment session, which “keeps improving over time,” she said. “At 12 weeks, we have clearance of over 80% of the lesions.”
At 12 months, they observed a 90% inflammatory lesion count reduction from baseline and a rapid response to treatment: a 73% reduction achieved after the first two treatment sessions. Histological studies revealed selective sebaceous gland destruction with no damage to the epidermis, surrounding dermis, or other follicular structures.
Dr. Sakamoto disclosed that she has received portions of patent royalties from Massachusetts General Hospital. Accure was cofounded by R. Rox Anderson, MD, the director of the Wellman Center.

The average lesion reduction at week 12 was 82% and the mean Visual Analog Scale score immediately after treatment was 2.10 out of 10. Each patient received more than 12,000 trigger pulls of energy from the device with no adverse events.
“This laser is absorbed in the near-infrared spectrum, so there is no melanin absorption,” Dr. Sakamoto explained. “It’s pretty much a color-blind laser, so we can treat darker skin types safely, with no side effects.” In other findings, researchers observed a 45% reduction in acne lesions after one treatment session, which “keeps improving over time,” she said. “At 12 weeks, we have clearance of over 80% of the lesions.”
At 12 months, they observed a 90% inflammatory lesion count reduction from baseline and a rapid response to treatment: a 73% reduction achieved after the first two treatment sessions. Histological studies revealed selective sebaceous gland destruction with no damage to the epidermis, surrounding dermis, or other follicular structures.
Dr. Sakamoto disclosed that she has received portions of patent royalties from Massachusetts General Hospital. Accure was cofounded by R. Rox Anderson, MD, the director of the Wellman Center.
FROM A LASER & AESTHETIC SKIN THERAPY COURSE
Selective cooling technology being used to remove age spots
, according to Arisa E. Ortiz, MD.
“What’s unique about this device is that I can see results without any downtime,” Dr. Ortiz, director of laser and cosmetic dermatology at the University of California, San Diego, said during a virtual course on laser and aesthetic skin therapy. “Most other devices are not like that. It was well tolerated; there was minimal pain. There was no postinflammatory hyperpigmentation; it really is customizable to the patients’ needs.”
First cleared by the Food and Drug Administration in 2016 to remove benign lesions of the skin, Glacial Rx received an expanded indication in 2020 to temporarily reduce pain, swelling, and inflammation. The device, which was developed by R2 Technologies, relies on cryomodulation, a concept developed at Massachusetts General Hospital and the Wellman Center for Photomedicine, Boston, to improve skin appearance and freeze melanin at the source. “Cryomodulation pauses melanin production, but the melanocyte function is preserved, the epidermal barrier is not disrupted, and there is no persistent inflammatory response, which is key, because it decreases the risk of postinflammatory hyperpigmentation, especially in darker skin types,” Dr. Ortiz said.
Here’s how it works: The handpiece of the device is placed on top of the skin and cooling is delivered to targeted solar lentigos and other benign lesions. Ice nucleation takes place within the dendrites. As cell turnover takes place, melanin-free cells migrate upward and appear as new skin. “Clinically, this appears as clearance of the lesion,” Dr. Ortiz said.
She discussed her clinical experience treating 15 patients with a beta version of the device. Since that time, Glacial Rx was redesigned to include a smaller-tipped handpiece, easier and faster prep time, and a proprietary water-based gel to facilitate ice crystal propagation, which is applied to the targeted lesions just prior to treatment.
For the trial at UCSD, the researchers performed 29 treatment sessions on 15 patients with Fitzpatrick skin types I-IV, to gain clinical experience and evaluate the effectiveness of the device. They found that the treatment was well tolerated, with minimal discomfort. The amount of heat extracted ranged from 107 to 166 kJ/cm2. No long-term dyschromia was observed, and some patients had lesion clearance after just one treatment.
“The settings are able to be titrated to where you have zero downtime, but you still get a lightening effect,” Dr. Ortiz said during the meeting, named “Laser & Aesthetic Skin Therapy: What’s the Truth?” sponsored by Harvard Medical School, Massachusetts General Hospital, and the Wellman Center for Photomedicine. “With other devices such as intense pulsed light, if you don’t see darkening than it probably didn’t work. With this device, you can titrate the length of the cooling and the temperature of the cooling.”
Posttreatment side effects commonly observed in the study were mild erythema, swelling, itching, and darkening. “There was minimal erythema in the higher settings, and some reports of itching and transient darkening in some of the higher settings,” she said.
Future indications for Glacial Rx may include psoriasis, acne, and rosacea. “We did try to use this for melasma,” she said. “It was effective, but I wouldn’t say it’s a cure for melasma. Melasma is very stubborn and requires a combination treatment, but it’s something we can use in our armamentarium.”
Dr. Ortiz reported having received consulting fees from R2 Technologies. She has been a paid consultant for and has received equipment from many device companies.

FROM A LASER & AESTHETIC SKIN THERAPY COURSE
Disinclined to offer laser hair removal? An expert makes the case to think otherwise
Omar A. Ibrahimi, MD, PhD, hears some dermatology colleagues say they don’t bother to offer laser hair removal in their practices because they figure that the procedure is under the purview of medical spas, but he sees it differently.
“I offer laser hair removal in my practice as a way to protect my patients from being picked off by medical spas,” Dr. Ibrahimi, a dermatologist and medical director of the Connecticut Skin Institute, said during a virtual course on laser and aesthetic skin therapy. “These patients are going to want to get laser hair removal. If they’re not going to have the opportunity to get it at your practice, they’re going to seek it elsewhere. When they go elsewhere, they’re going to be picked off for other procedures as well.”
First developed in 1995 by R. Rox Anderson, MD, and colleagues at The Wellman Center for Photomedicine, laser hair removal has become the gold standard for permanent hair destruction, and ranks as the most common energy-based procedure performed in the world, Dr. Ibrahimi said. “Results are very long lasting and durable beyond 2 years after treatment,” he said. “These patients tend to be highly satisfied and have permanence with these treatments.”
Treatment goal, patient selection
While the target chromophore for the procedure is melanin, the goal is to destroy the stem cells located in the hair bulge and the hair bulb. “This is technically called the extended theory of selective photothermolysis, but it’s the same concept except that our target chromophore and our desired target for destruction are slightly spatially separated,” he said.
Proper patient selection is key, so a focused medical history and physical exam are essential prior to the procedure. If unwanted hair is located on the face, jawline, or chest of a female, consider and ask about potential endocrine-related dysfunctions such as polycystic ovary syndrome (PCOS). “Getting those addressed can often help the hypertrichosis as well,” he said. “Another condition is explosive hypertrichosis where hair growth starts very suddenly. It’s uncommon but it’s something to think about.”
Pregnancy is not an absolute contraindication for laser hair removal, Dr. Ibrahimi continued, but he elects not to perform the procedure on pregnant patients. He also asks patients about any history of photosensitivity, active infection at the intended treatment site, keloids, or hypertrophic scarring. Past methods of hair removal also matter. “What we’re targeting is the pigment in the hair shafts,” he said. “So, if your patient is waxing or plucking or epilating or removing the hair in some manner, they’re actually removing the target chromophore.”
Patients with darker Fitzpatrick skin types can be treated safely but tanned individuals face a risk of complications because of active melanocytes. “As we approach summer in New England, we slow down the amount of hair removal we do because it’s a riskier procedure,” he said. “I recommend that my patients not get any significant amount of sun exposure a month before or after treatment.”
The color and quality of hair also drive treatment success. Black and brown terminal hairs absorb the millisecond laser energy, but white, gray, red, and light blond hairs lack adequate melanin to make them suitable target chromophores.
Excessive and unwanted body hair ranges in severity and can usually be classified as either hypertrichosis or hirsutism.
The desired clinical endpoint is perifollicular edema and erythema. Treatment parameters that can be varied with Food and Drug Administration–cleared devices include wavelength, fluence, pulse duration, spot size, and skin cooling. The most popular devices are the Alexandrite 755 nm laser; the diode 800 nm laser; and the 1064 nm Nd:YAG laser, which is safe for all skin types. “Often you have to use higher relative fluences to treat patients with the 1064 nm Nd:YAG because on the absorption spectrum, the 1064-nm wavelength has a relatively lower absorption for melanin compared to the alexandrite. However, you can still get effective, long-term hair reduction with the Nd:YAG laser,” he said (Arch Dermatol. 2008 Oct;144[10]:1323-7).
More recently, Dr. Ibrahimi and colleagues found that a 1060-nm diode laser system with multiple handpieces for permanent hair reduction was safe for all skin types, in an open label prospective study.
Higher fluences have been correlated with greater rates of permanent hair removal, but they also are more likely to cause undesired side effects. Dr. Ibrahimi advises clinicians new to laser hair removal to conduct a few different test spots and look for the desired clinical endpoint of perifollicular erythema and edema. “The highest fluence that gives you that endpoint without any adverse reactions is going to the best fluence for treatment,” he said at the meeting, which was named “Laser & Aesthetic Skin Therapy: What’s the Truth” and was sponsored by Harvard Medical School, Massachusetts General Hospital, and the Wellman Center for Photomedicine. “Do a few test spots, bring them back a week later and see which ones were tolerated well without any side effects and which weren’t. That gives you a good starting point for your treatment.”
Cooling down the epidermal melanin not only keeps the procedure safe, it’s a salve for pain. “There are a variety of methods of passive and active cooling,” said Dr. Ibrahimi, a member of the American Society for Dermatologic Surgery board of directors. “You can use something as simple as cold gel, but the active methods are better because once the method of passive application of cold gel warms up, you lose that cooling effect. You can use forced chilled air. Many commercial devices come with a cold tip which cools down the epidermal melanin. Others use dynamic cooling, which emit cryogen spray from a separate part of the handpiece. It hits right where the laser pulse is going to go, is absorbed by the skin, and it cools down the epidermal melanin.”
Treatment complications
Complications that can occur from treatment include pigmentary changes such as hyperpigmentation and hypopigmentation. “In lighter skinned individuals, sometimes excess fluence can lead to an erythematous appearance,” he said. “In darker-skinned individuals, this often manifests as hyperpigmentation and can be very long-lasting.” Dr. Ibrahimi ranks improper technique as a complication, “because ideally you want to lay your pulses down with 10%-15% overlap during treatment,” he explained. “If you don’t overlap, you’re going to have zones that don’t get any of the laser photons. If you do, then your patient is not going to be happy with you.”
Paradoxical hypertrichosis occurs in 1%-5% of patients, typically in women from Mediterranean, Middle Eastern, or South Asian ethnic backgrounds. This tends to develop on the lateral or jawline part of the face. “Often it occurs in the setting where they come in and want these vellus hairs treated,” he said. “Somehow the laser, instead of destroying the hair shaft, triggers it and stimulates it and can’t differentiate a vellus hair from a terminal hair. This is important to discuss during your informed consent, especially when you’re treating on the lateral jawline or the sideburn area. If this happens, you can treat through it.”
Transgender patients and future directions
Dr. Ibrahimi pointed out that increasing numbers of transgender patients are visiting dermatologists seeking laser hair removal. About 16 million Americans are estimated to have a gender identity that differs from the one assigned to them at birth, yet they face several barriers to care, “ranging from ignorance on our end to maybe our own biases being transposed onto these patients,” he said. “We really need to do a better job for them. We really have an obligation to provide good care for all of our patients.”
Transgender women typically seek hair removal on the face and neck as well as in the genital area to remove hairs in preparation for vaginoplasty. Transgender men typically seek hair reduction on the forearm or on the thigh, because those are graft sites in preparation for phalloplasty. As a resource for transgender care, he recommends the UCSF Transgender Care website.
As for future directions in the field, Dr. Ibrahimi predicted that hair removal devices for home use will continue to improve and become more widespread. “This raises a host of considerations, from the risk of eye damage to the risk for paradoxical hypertrichosis, and what happens when pigmented lesions get treated with these low-powered machines compared to the ones we have in our office,” he said. “I also think we’re going to see office-based devices with larger spot sizes, smarter devices that are capable of taking over more of the functions we do. I’m most excited about the potential for treating nonpigmented white hair or poorly pigmented blond or reddish hair in the future.”
Dr. Ibrahimi disclosed that he has received research funding and speaker honoraria from Lutronic, Lumenis, Cutera, and Syneron-Candela. He also holds stock in AVAVA Inc.

If you do, then your patient is not going to be happy with you.”
Paradoxical hypertrichosis occurs in 1%-5% of patients, typically in women from Mediterranean, Middle Eastern, or South Asian ethnic backgrounds. This tends to develop on the lateral or jawline part of the face. “Often it occurs in the setting where they come in and want these vellus hairs treated,” he said. “Somehow the laser, instead of destroying the hair shaft, triggers it and stimulates it and can’t differentiate a vellus hair from a terminal hair. This is important to discuss during your informed consent, especially when you’re treating on the lateral jawline or the sideburn area. If this happens, you can treat through it.”
Transgender patients and future directions
Dr. Ibrahimi pointed out that increasing numbers of transgender patients are visiting dermatologists seeking laser hair removal. About 16 million Americans are estimated to have a gender identity that differs from the one assigned to them at birth, yet they face several barriers to care, “ranging from ignorance on our end to maybe our own biases being transposed onto these patients,” he said. “We really need to do a better job for them. We really have an obligation to provide good care for all of our patients.”
Transgender women typically seek hair removal on the face and neck as well as in the genital area to remove hairs in preparation for vaginoplasty. Transgender men typically seek hair reduction on the forearm or on the thigh, because those are graft sites in preparation for phalloplasty. As a resource for transgender care, he recommends the UCSF Transgender Care website.
As for future directions in the field, Dr. Ibrahimi predicted that hair removal devices for home use will continue to improve and become more widespread. “This raises a host of considerations, from the risk of eye damage to the risk for paradoxical hypertrichosis, and what happens when pigmented lesions get treated with these low-powered machines compared to the ones we have in our office,” he said. “I also think we’re going to see office-based devices with larger spot sizes, smarter devices that are capable of taking over more of the functions we do. I’m most excited about the potential for treating nonpigmented white hair or poorly pigmented blond or reddish hair in the future.”
Dr. Ibrahimi disclosed that he has received research funding and speaker honoraria from Lutronic, Lumenis, Cutera, and Syneron-Candela. He also holds stock in AVAVA Inc.
